django static files do not work for one application only

Question

My django application works well except for one application, all the static files are not loaded.

That happens on this url: http://localhost/db_mgmt/add/dg/. The template is loaded, but no css, no js. When I look at one of the errors, the browser tries to load the page http://localhost/db_mgmt/add/static/jquery.min.js but the link should be: http://localhost/static/jquery.min.js These files are loaded in base.html and work everywhere else...

Example of inclusion in base.html:

<script type="text/javascript" src="{{ STATIC_URL }}jquery.min.js"></script>

Here is my settings.py if it helps:

# Django settings for europolix project.
from django.conf.global_settings import TEMPLATE_CONTEXT_PROCESSORS as TCP

import os
#root of the project
PROJECT_ROOT=os.path.abspath(os.path.join(os.path.dirname(__file__), os.pardir))
#root of templates
TEMPLATE_ROOT=os.path.join(PROJECT_ROOT, 'templates')
#root of media files (import / export files)
MEDIA_ROOT=os.path.join(PROJECT_ROOT, 'media')
#root of static files (css, js, jquery...)
STATIC_ROOT=os.path.join(PROJECT_ROOT, 'static')
#WEB_ROOT=url of WSGIScriptAlias given in the apache configuration file (/etc/apache2/apache2.conf in Lubuntu 13.04)
#example: WSGIScriptAlias /europolix /var/www/europolix/europolix/wsgi.py -> WEB_ROOT="/europolix"
#in the apache configuration file, you must update the alias for static files as well
#ex: Alias /europolix/static /var/www/europolix/static -> WEB_ROOT="/europolix"
WEB_ROOT="/europolix"
#local
WEB_ROOT=".."
# URL that handles the media served from MEDIA_ROOT. Make sure to use a
# trailing slash.
# Examples: "http://media.actrence.com/media/", "http://example.com/media/"
MEDIA_URL=WEB_ROOT+'/media/'

# URL prefix for static files.
# Example: "http://media.actrence.com/static/"
STATIC_URL=WEB_ROOT+'/static/'

# Additional locations of static files

STATICFILES_DIRS=(
    STATIC_ROOT,
    # Put strings here, like "/home/html/static" or "C:/www/django/static".
    # Always use forward slashes, even on Windows.
    # Don't forget to use absolute paths, not relative paths.
)

TEMPLATE_DIRS=(
    TEMPLATE_ROOT
    # Put strings here, like "/home/html/django_templates" or "C:/www/django/templates".
    # Always use forward slashes, even on Windows.
    # Don't forget to use absolute paths, not relative paths.
)

If I print those variables in my view I have the following paths:

PROJECT_ROOT /var/www/europolix
STATIC_ROOT /var/www/europolix/static
STATIC_URL ../static/
WEB_ROOT ..

Thanks in advance for your help.

Edit :

The variable WEB_ROOT is relative in local. Could it be the problem? The variable searches in the parent directory (am I right?). So the applications with only one "child" in the url work (http://localhost/act or http://localhost/export) but not the applications with many "children" (e.g.: the one above, http://localhost/db_mgmt/add/dg/)

urls.py of the export app:

urlpatterns=patterns('export.views',
    url(r'^/?$', 'export', name='export'),
)

urls.py of the db_mgmt app that does not work well:

urlpatterns=patterns('db_mgmt.views',
    url(r'^add/(?P<field>\w+)/$', 'add', name='add'),
    url(r'^form_add.html/(?P<field>\w+)/$', 'form_add', name='form_add'),
)

Answer 1

As I thought, the problem, one of the problems was about the WEB_ROOT variable. Here is how I fixed it:

WEB_ROOT="http://127.0.0.1:8000"

Another problem was the path of the template of my application db_mgmt:

url="/db_mgmt/form_add.html/"+field+"/"

I had to remove the first slash to have it work:

url="db_mgmt/form_add.html/"+field+"/"

Solved :).

We would need to know more about the differences between the applications that work and the application that is giving you trouble
